備註: 香港攝 Four new additions and a taxonomic amendment to the orchid flora of Hong Kong 插天山羊耳蒜應該是羊耳蒜屬當中植株最大型者,為大型地生蘭。肉質莖,圓柱狀肥厚,並有節。葉3-5片,寬大並曲摺形態,歪斜。花葶粗長,可達20cm。花莖綠色,具翼狀稜脊,花色初時為綠,之後漸變淡褐黃,藥帽黃綠,唇瓣倒卵形至楔形,先端具明顯細鋸齒緣。生境於中海拔林下泥土斜坡,有散射光,多霧濕。冬天葉片全枯萎,到早春2月抽出新葉,花期4月。此品種為日本人福山伯明于1933年5月在臺灣桃園南插天山採得,先命名為黃花羊耳蒜。到1972年臺灣改稱為插天山羊耳蒜。而香港是近年才發現,分佈極窄。保育評級應是「極危」。 (香港似乎只有朱劍虹老師的蘭花書本有介紹它,其他資料來源貧乏!台灣則有較多介紹。)thanks kingsir's info FOC: Herbs, terrestrial.
